What YAML structures are supported?

The tool supports flat key-value YAML and one level of nested objects (which become INI sections). Deeply nested objects are serialized as JSON strings to preserve data.

How are YAML arrays handled?

Arrays are converted to comma-separated values on a single INI line. For example, `ports: [80, 443]` becomes `ports = 80, 443`.

What happens to root-level scalar values?

Root-level key-value pairs that are not under an object are placed under a [general] section at the top of the INI output.

Is my data sent to a server?

No. All conversion happens entirely in your browser using the js-yaml library. No data is transmitted anywhere.

What are the limitations of INI format?

INI does not support deep nesting, typed values, or complex data structures. Values are always strings. This converter handles one level of nesting; deeper structures are serialized as JSON.

Can I convert INI back to YAML?

This tool only converts YAML to INI. For the reverse, use our INI to YAML converter tool.

Summary

Paste YAML configuration and instantly convert it to INI format with full section and key-value support.

How it works

Paste or type your YAML configuration into the input panel.
The converter parses the YAML using a client-side JS-YAML library.
Top-level YAML objects become INI section headers like [section].
Nested scalar values are written as key = value pairs under their section.
Arrays are serialized as comma-separated values.
Click "Copy INI" to copy the result to your clipboard.

Use cases

Migrate application config from YAML to INI format.
Convert Docker or Kubernetes environment configs to legacy INI files.
Prepare configuration for tools that only accept INI format (e.g., PHP, Python configparser).
Quickly inspect what an INI representation of a YAML file would look like.
Onboard legacy applications that require Windows-style INI configuration.
Generate PHP php.ini-style config snippets from YAML sources.
